Any ideas when the new Veeam build will be released with this hotfix already in it? We don't want to deploy the build that needs so many hotfixes and out lab testing showed that we would be affected by 3 issues that require 3 separate hotfixes. Any timeline information on the fully tested release with this issue fixed would be greatly appreciated.

Yeah, unfortunately we will have to stay with 9.5U2 for now since we are not experiencing any issues with that release now and it looks like we would need to open at least 4 support cases for 4 different hotfixes:

It is my understanding that the hotfixes are not tested nearly as exhaustively as a full release and we don't want to upgrade and then start installing a bunch of hotfixes that may cause further issues.

We are faced with the same issue , SBS 2011 , updated to 9.5 U3 about three weeks ago.
Since last week, VSS network timeout error, we have reboot the server. It doesn't come right with this too , need to restart Exchange information store, after restart.
Then with the scheduled backup , it may fail once or twice or thrice and give up as total failure OR it may go through successfully in the second or third retry
Then the backup may work. Until of 9.5 U2 , things were like clock work.
